CHARLES K. PIGKLES, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORTO JOHN A. BRILL, OF PHILADELPHIA, PENNSYLVANIA.

SWING-BACK CAR-SEAT.

of Pennsylvania, have invented a new and useful Swing-Back Car-Seat, of which the following is a specification.

The object of my invention is to produce a reversible car-seat in which the back and cushion move in the same direction, the main purpose of which is to conserve space in the location and operation of car seats. This broad invention is not mine, but forms the subject-matter of an application filed May 28, 1903, Serial No. 159,055, by William H. Heulings, J r.; and my invention is limited to such broad invention as will be hereinafter set forth.

For a more particular description of one embodiment of my invention reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is a front elevation of a car-seat embodying one form of my invention, parts being broken away to more clearly disclose the structure. Fig. 2 is a side elevation of a car-seat embodying my improvements with parts broken away. Fig. 3 is an end elevation showing the cushion and back in their central position while the seat is being reversed. Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3 looking in the direction of the arrows. Fig. 5 is an end elevation of Figs. 6, 7, 8, 9, 10, and 11 are views showing certain details of construction.

Throughout the various views similar reference characters designate similar parts.

The swing-back seat 1 is provided with any suitable support 2, at the top of which arthe cross-rails 3, which are united by means of the end plates 4, to which links 5 and 6 are pivoted. The plates 4 are provided with perforations 4* adjacent to each end, through which bolts pass to secure them to the crossrails 3, and the plates are also provided with centrally-located perforations 4 and 4", the former being below the latter. The perforations 4 form a bearing for a shaft 14, and the perforations 4 receive stud-pins 13, which are preferably swaged therein. The links are enlarged near their lower ends and provided with segments of annular gears 7, whlch are concentrlc wlth their lower pivots Specification of Letters Patent.

Application filed May 28,1903. Serial No. 159,077.

8, and in the outer walls of these links, between the said pivots 8 and annular gears 7, are slots. 10. The ends of the said gears 7 rest on one or the other of the cross-pieces 3, and s0 limit the throw of movement of the links. The links 6 are provided with spurgears 11 at their lower ends, which are concentric with their pivots 12, which engage studs that are fixed in the upper portions of the plates 4. The parts are so proportioned and arranged that the stud 13 passes through the slot 10, and the gears 7 and 11 mesh to gether, so that the links always move in the same direction. The links are always moved together. The links 6 are provided with proj ecting lugs 15, the purpose of which will be explained below.

Each of the cross-rails 3 is provided with two brackets 16, which are secured to said rails by means of screws, and said brackets are provided with upwardly-projecting parallel and perforated ears 17. Pins 18 pass through the said perforations and secure the cushion-supports 19 by means of curved openings or slots 20 in their vertical webs 21. Bent plates 22 are fixed to the centers of the ends of the cushions 23 by screws 22 and the plates 22 engage the lug 15 and cause the cushion 23 to move in unison with the links. This cushion 23 may be made in any desired way and forms no part of my invention.

The free ends 24 of the links 5 are pivoted to the studs 25 on the plates 26, which are fixed to the edges of the back 27. The plates 26 are offset at 28 and provided with a slot 29, in which slides a pin 30, which is fixed at one end of the link 6. The links 5 engage the outer surface of the plates 26 and are slightly offset at 31, so as to swing clear of the lower ends of said plates, and the links 6 are secured to the inner surfaces of said plates and have a pivoted and sliding engagement with them. This construction permits the links to swing without interference with each other except that'caused by the intermeshing of the gears. A holdingstrap 32 may be secured to the back 27.

From this description the operation of my improved seat is obvious. Assuming the parts to be in the position indicated in Fig. 2 and the seat is to be reversed, the back is thrown into the position indicated in Fig. 3 and then on to the left of the cushion. This movement of the back causes the links 5 to rotate the links 6, which in turn move the cushion 23 in the same direction as the back 27 and give the cushion 23 its proper inclination because of the slotted supports 19. When the seat is returned to its initial position, the same movements take place in the opposite direction, and while the back is shifted from one position to the other it is raised by the links 5 until it'is clear of the cushion and remains clear until the movement terminates. The links 5 and 6 are connected by gears and the links 5 by the shaft 14, so that all parts are positively connected and act together. I

While I have shown and described one embodiment of my invention, it is obvious that it may be embodied in many other forms, all

of which come within the scope of my invention and are covered by the following claims. Having thus described my invention, what I claim is 1.
